Powerful solar flare temporarily disrupts communications on Earth

SPACE – The sun erupted with a massive solar flare late Thursday (April 24), triggering a temporary communications blackout on some parts of Earth. The powerful flare peaked at 8:27 p.m. EDT Thursday (0027 April 25 GMT), and ranked as an X1.3-class solar storm, one of the strongest types of flares the sun can experience, according to a report from the U.S. Space Weather Prediction Center. NASA’s sun-watching Solar Dynamics Observatory captured video of the intense solar flare in several difference wavelengths. The solar flare erupted from an active sunspot region known as Region 2035 located on the far western side (or limb) of the sun as seen from Earth. Because of its position, the flare sparked a high-frequency radio blackout for about an hour on the daytime side of Earth, most likely over the Pacific Ocean and Eastern Pacific Rim, according to the SWPC update. Thursday’s solar flare was the fourth X-class solar flare of 2014. It followed an X1.2 solar flare on Jan. 7, a monster X4.9 solar flare on Feb. 24, as well as an X1 solar flare on March 29. While X-class flares are the most powerful eruptions on the sun, the star also experiences more moderate M-class solar flares (which can supercharge Earth’s aurora displays) and weaker C-class storms. The sun is currently in an active phase of its 11-year weather cycle, and was expected to reach its peak activity in 2013. –Space
